The Faxon Firearms Duty Series threaded barrel for the Sig Sauer P365 XL brings upgrade-ready performance to your carry or duty 9mm. Built from chrome moly vanadium steel and finished in black nitride, this replacement barrel gives you the option to run a suppressor while maintaining the reliability and fit your P365 XL demands. Whether you're looking to reduce recoil impulse, lower noise signature, or simply want the flexibility that a threaded muzzle provides, this is a straightforward bolt-in solution that respects the tight tolerances your compact 9mm is known for.
Faxon has earned a solid reputation for no-nonsense barrel work. The Duty Series line reflects that ethos—no marketing fluff, just quality steel and consistent manufacturing. The chrome moly vanadium construction and nitride finish are proven materials that stand up to years of shooting, cleaning, and storage without sacrificing durability or corrosion resistance. If you run your P365 XL hard or plan to suppress it, this barrel is built to handle both.
Installation is straightforward for anyone comfortable swapping a barrel. The threaded muzzle is cut for standard suppressor mounts, so you'll have options when you're ready to pair it with cans from most mainstream manufacturers. This is the kind of upgrade that pays dividends in versatility without asking you to compromise on the compact, reliable platform you already trust.
